A Survey of Physical-layer Authentication Enhanced by Emerging Spatial Domain Technologies
Yuhao Chen, Boxiang He, Junshan Luo +7
This article surveys spatial-domain-enhanced Physical-layer Authentication (PLA), with Dual-polarized Antennas (DPA), Massive Multiple-Input Multiple-Output (MIMO), and Reconfigura…
FAS-aided Robust Anti-Jamming Communications: Continuous and Discrete Positioning Designs
Yifan Guo, Junshan Luo, Shilian Wang +1
This paper investigates the joint optimization of beamforming and antenna positions in fluid antenna system (FAS)-aided anti-jamming communications. We consider a multi-user multip…
Specific Multi-emitter Identification: Theoretical Limits and Low-complexity Design
Yuhao Chen, Boxiang He, Junshan Luo +3
Specific emitter identification (SEI) distinguishes emitters by utilizing hardware-induced signal imperfections. However, conventional SEI techniques are primarily designed for sin…
Fluid-Antenna-aided AAV Secure Communications in Eavesdropper Uncertain Location
Yingjie Wu, Junshan Luo, Weiyu Chen +3
For autonomous aerial vehicle (AAV) secure communications, traditional designs based on fixed position antenna (FPA) lack sufficient spatial degrees of freedom (DoF), which leaves…
Dual-end Fluid Antennas For Robust Anti-jamming in Low-altitude Air-ground Communications
Yifan Guo, Junshan Luo, Fanggang Wang +3
This paper addresses the challenge of co-channel interference and intentional jamming in low-altitude air-ground communications. Since conventional fixed-position antenna (FPA) sys…
